    摘要: An integrated LCC-based strain gage sensor, in which at least two LCC traces or strands run across a microcavity within the cylinder head gasket. In one aspect of the present invention, a system is provided comprising a signal source and a microcavity through which an input signal from the signal source passes and which alters the input signal as a result of a response of the microcavity to a strain. An LCC connects the microcavity and the signal source and an input signal propagates through the LCC. The microcavity may comprise one or more reflective surfaces which alters the input signal as a result of a change in a dimension of the microcavity. In another aspect of the invention, the microcavity produces an output signal that has an intensity or frequency different from that of the input signal upon undergoing a deformation.

    摘要: In a pressure sensor made by bonding a sensor chip and a metal stem together with a resin adhesive, fluctuation of the sensor output caused by temperature changes are maximally reduced. The resin adhesive for bonding together the sensor element and the metal stem has a creep characteristic defined as CRnullAnullnullB between its creep rate CR and stress null upon it with A and B being constants. The resin adhesive is selected to satisfy that the constant B is not greater than 3.5.

    摘要: It is an object of the present invention to provide a portable pressure measuring apparatus to be used as an altimeter, which can be automatically switched to an optimum sampling period in accordance with a use of the apparatus before a pressure measurement at all times. A portable pressure measuring apparatus additionally comprises a pressure/altitude operation section for obtaining an altitude from a measured pressure by an arithmetic operation, a rate of pressure change operation section, and a movement detecting section, wherein, if the movement detecting section detects a movement, a pressure is measured in a sampling period, for example, in a 1-second sampling period, if a rate of altitude change is equal to or greater than a threshold or in a sampling period, for example, in a 5-second sampling period, if the rate of altitude change is smaller than the threshold and wherein, unless the movement detecting section detects any movement, the pressure sampling measurement is not performed.

    摘要: Support members are provided on the terminal portions of a sensor main body. In this state, a seal portion is formed by molding, and the seal portion seals the terminal portions of the sensor main body. During molding, external pressure acts on a housing. However, since four electrode wires pulled out from the housing are supported by insulating support members, the four electrode wires do not contact one another due to the pressure applied during molding, and thus do not short-circuit.
